smythmyke/patent-search-mcp-server

MCP (Model Context Protocol) server for the **AI Patent Search Generator** — patent dossiers, prosecution history, Office Action AI analysis, citation/family/CPC lookups, plus a **legal-intelligence layer** (PTAB validity challenges, district-court litigation, company-litigation lookup, legal status, chain of title, term) and a one-shot **AI risk profile**. All from USPTO public data. Works in Claude Code, Claude Desktop, Cursor, ChatGPT-with-MCP, and any other MCP-compatible client.
26 tools available.
- **Patent data:** dossier, claims, claim_chart, prosecution, prosecution_timeline, oa_analyze, examiner, attorney, entity_status, term, assignments, legal_status, pregrant_pub, query, search, similar, citations, family, cpc, cpc_suggest, balance.
- **Legal intelligence (new):** challenges (PTAB validity challenges — who attacked the patent and did it survive), litigation (US district-court infringement suits — who sued whom), company_litigation (reverse lookup: all patent suits involving a company).
Prerequisites
1. Install the AI Patent Search Generator Chrome extension and sign in.
2. Generate an API key from the extension's **Admin** tab.
3. Node.js 18+ (only required for local installs; npx-style configs don't need a local install).
